1.       What are the functions of the pulp: nutrition from bloodstream, defensive fx.- inflammatory rx. To any kind of change, sensory- sensitive to external stimulus, only feel pain not hot & cold, formation- forms organic makeup of dentin and secondary dentin.

2.       List the 4 types of pulp: coronal pulp, radicular pulp, apical foramen, accessory canal.

3.       Opening of pulp at apex of tooth. Allows entrance & exit from PDL: Apical foramen.

4.       Located in crown of tooth- pulp horns located here, # of horns depends on # of cusps: Coronal pulp.

5.       Located in root area. Opening (apical foramen)& maybe accessory canal: radicular pulp.

6.       If you have several apical canals the largest is designated the apical foramen & the lateral ones are called: accessory canals.

7.       What is the cause of an accessory canal? Occur from a root sheath encountering a blood vessel during root formation. Opening from pulp to PDL.

8.       Odontoblastic zone- lines outer pulpal wall & can form secondary or tertiary dentin.

9.       Cell free zone- looks cell free under microscope but does have blood & nerve supply. Need a very high-powered microscope to see.

10.  Cell rich zone- extensive supply of cells & extensive nerve & blood supply.

11.  Pulpal core- inner most zone, extensive nerve & blood supply zone. Similar to cell rich zone.
